Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472488, here are decompositions:

137 + 31472351 = 31472488
149 + 31472339 = 31472488
197 + 31472291 = 31472488
227 + 31472261 = 31472488
419 + 31472069 = 31472488
521 + 31471967 = 31472488
587 + 31471901 = 31472488
701 + 31471787 = 31472488

Showing the first eight; more decompositions exist.
